Find out if it has a computer, my guess is it does being an ‘87? How are you going to get your gasoline?
Get a Horse or an extra pair of walking shoes and a Bicycle.
Just turn you home into a giant Faraday Cage and disconnect from the power grid and you are home free.
Of course there wouldn’t be an internet, and you will be under siege if everyone can see you have your AC going.
“how will you get gasoline”
I only need enough to get into town, 40 miles, collect family members and get home. If the effect on autos is nearly as damaging as I’ve been led to believe there will not be much of a post event demand for gas. I suppose if the EMP proof truck was a good idea I would only need to siphon fuel from the thousands of stalled autos littering the roads.
